My Family Contact Group is still intact but the menus have changed and I can't seem to find a way to move it back to a Home Screen or even change it with the Favorites Group which is on the Home Screen and I don't need. Thanks.
I had the same problem and just figured out how to fix it.
You will get options to 'Select a group for widget' or 'Edit group.'
If you choose 'Select a group for widget,' it will pull up your list of contact groups.
Choose the one you wish to display.
